Renewed January 16, 1934 10 Claims.

This invention appertains to improvements in combined window sash operators and locks generally and more particularly to types. thereof adapted for use in connection with the sash of casement windows and the like. I I

An object of the invention is to provide an extremely simple but effective and durable means for operating outwardly swinging casement Window sash fro-mthe inside of a room whereby a sash can be unlocked, moved from a closed to any open position or vice versa-and relocked'in a selected position, all in a single operation. I

Another object of the invention resides in the provision of a means of the class set forth whereby the sash of a screened casement window may be operated to any desired positionof use and locked in such position from the inside of a room and without disturbing the screen in'any way for the purpose. e

A further object of the invention lies in the provision of a means as hereinbefore characterized, which is of a'construction and design to adapt the same for installation, with equal facility, on casementsof various sizes and of either wood or metal construction. j I

With the foregoing and other equally important objects and advantages in view, the invention resides in the certain newand useful combination, construction and arrangement of parts, as will be hereinafter more fully described, set forth in the appended claims, and illustrated in the accompanying drawings in which Figure 1 is a horizontal section through a conventional type of screened casement window, showing a practical and preferred embodiment of the improved combination sash operator and look as it appears when installed on each of the two sash of the Window, one of the sash being disposed in fully opened position,

Figure 10 is a vertical transverse section taken on the line 10l0 of Figure 9. r w

Referring to the drawings, wherein like char,- acters of reference designate corresponding parts in the several views thereof, and more particularly to Figures 1 to 5 inclusive, the embodiment of the invention, as shown therein by way of example only, is constituted in a member 11, such as a bar, rod or strap, preferably of metal, which, is mounted crosswise of the frame of a casement sash b in such manner as to not in any way interfere with opening and closing move ments of the sash. A similar member 12 is mounted crosswise of the opening in the casing a of the window and substantially in the plane of the member 11 carried by the sash b.

Ihe member 12 has a boxing 13 attached at 0 an intermediate point thereon and houses a swivel 14 within the same. The outer and inner: sides of the boxing 13 are open and the swivel 14 has an elliptically shaped passage'l5 extending horizontally therethrough in line with the open sides of the boxing, the major axis of the passage 15 being vertical. The swivel 14 is pro,- vided with mountings 16 on its upper and'lower ends which may each be in the form of a boss, a pin or a screwed connection for engagement in suitable openings formed in the upper and lower sides of the boxing 13. l

The member 11 is secured in place at the inner side of the sash frame 2) and is provided with a vertical pin 17 upon which a rod end 18 ispivotally mounted. A hinged rod section 19 is adjustably attached to the rod end 18 by means of a screw threaded portion 20. I a

The operator rod, of which the section 19 is a part, is made up of a number of addedhinged sections 19, the combined length of which, when the several sections are disposed in aligned relation, is sufficient to allow the outwardly hinged sash b to swing to fully opened position, when the rod'is manipulated from the inside of a room.. These rod sections are preferably round in cross section but they may be square or rectangular as desired.

The hinged connections shown are each of the tongue and grooved type with a pivot pin 21 attaching mating members. As shown, the tongue portion 22 of each connection has an oppositely beveled end in order to'allow clearance for hinging movements of adjacent and sections and whereby the beveled portion 23 ,will' the wall at the inner end of the grooved portion of an adjacent rod section. Also the lower corner portions of the opposite side portions of the grooved ends of the rod sections are preferably rounded off, as at 23', to lend further clearance for the proper hinging movements of the hinge connections. 7

A lateral slot 25 is formed on the lower side of each rod section 19 and. operates over a lock pin 26 placed in the swivel 14. to hold the rod in any adjusted position in the passage 15. In Figure 1, the hinged rod 19 is shown with four added sections 19', although the number of sections may be varied as desired; the greater number of such sections operating to give closer adjustment to the degree in which the swinging sash may be opened or closed and locked.

In use, the jointed rod acts in'compression or tension to open or close the sash, and an angled or open joint at the top of the inner pendant portion of the rod is per se a locking means for sustaining the parts and sash in selected adjusted position of operation, and in addition the hinge connections in the rod serves to dispose the surplus extension of the latter into the room and allows it to drop into a depending position out of the way, which surplus will be determined by the degree of opening of the sash b.

In operating theswinging sash b from a closed position, as shown at the right hand side of Figure 1, to an open position, as shown at the left hand side thereof, the inner pendant end portion of the rod 19 is raised in an arced movement about the uppermost pivot pin 18 until the several rod sections 19', are disposed in a straight or horizontal position and in line with the outer end section aforesaid. In this movement, the tongue portion 22, operating about the hinge pin 21 of the upper joint at the moment, strikes the cross pin 26 and raises the rod section passing outwardly through the passage 15 inthe swivel 14 in'a manner to free the lateral slot 25 from the cross pin, when the rod T 19, in its entirety, is free to be moved in either fore or aft direction through the swivel 14. This fore or aft movement of the rod swings the sash b to a fully opened, fully closed or intermediate open positions as desired.

The free end of the inner end rod section 19' is preferably provided with a knob or handle portion 27 to facilitate the manipulation of the operator rod, and the same is preferably made from a resilient material, such as rubber or the like, in order that, when a desired position of rest of the sash b is reached and the inner surplus portion of the rod 19 is allowed to drop downward, it will act as a bumper to prevent otherwise possible breakage of the sash glass, particularly in the event of the screen being removed.

Projecting inwardly from the upper side of the inner end of the boxing 13 is an extension 28 which acts to hold the pendant portion of the rod 19 in vertical position and against vertical movement during non-use. By thus preventing the vertical movement aforesaid, the lateral slot 25 in the rod section 19', at rest in the swivel 14 at the moment, remains engaged with the cross pin 26. This'extension 28 is preferably of spring material and consequently allows the rod, when accidently knocked sideways, a certain freedom of movement without disturbing its locking effort.

In order to form an insect-proof enclosure, a

screen 0 is positioned interiorly of each casement opening in a usual manner, and the same has a light metal frame 29 placed about an opening in the screen fabric and in a position to snugly fit over the inner end portion of the boxing 13. Thus, the operating rod 19 may be manipulated as hereinbefore stated without removing the screen from operative position, since the inner end thereby will project directly from the boxing into the room. Also, this arrangement readily admits of the screen being removed from the window Without dismantling the operator. This is to be accomplished by merely bringing a pendant portion of the rod 19 into aligned relation to that portion extending outwardly through the boxing 13, when the framed opening 29 may be readily freed from the boxing and inner rod end by a natural withdrawal of the screen from a casement opening.

Also, a hinged member or plate 30 is pivoted interiorly of the upper portion of the passage 15 in the swivel and in such manner that it rides loosely on the rod 19 to prevent the ingress of insects at all times.

As best shown in Figures 2 and 3, the pivot pin 17 rising from the attaching member 11 at the inner side of the sash b, may have its upper end headed as at 31 to prevent any possible disengagement of the rod connection 18 therefrom after an assembly of the parts of the device is completed. The length of the pin 17 is greater than that of the bore of the rod end connection 18 in order to compensate for any sagging or lift of a sash on its hinge supporting connections with the casing a and to thereby prevent any interference with the alignment of the rod 19. Also, the bar 11 is preferably unattached to the sash 1), except at its ends which are secured to the opposite vertical sides of the frame of the sash. Each of the members or bars 11 and 12 have a sufficient resiliency or spring to compensate for the normal vertical movements of the rod end connection 18 on the pivot pin 17 demanded by the required aligning of the rod 19 relatively to the swivel during the outward and inward swinging movements of a sash b. This resiliency of spring action of the bars 11 and 12 also tends to prevent any possible binding of the connection 18 on the pivot pin 1'7, as is obvious.

In the modified form of the operator as shown in Figure 6, the swivel 14' is here mounted between spaced oppositely angled members 12' extending horizontally of the window opening, after the manner of the member 12 in the first instance of the invention. In this arrangement, a spring metal. plate 28 is inserted in place between the upper angled member and the swivel 14' to function after themanner of the spring extension 28 aforesaid in preventing accidental vertical movement of the operator rod 19.

These swivel supports 12 and 12 may be of uniform cross-section throughout their length, or slightly tapered in opposite directions toward their ends, somewhat as shown in Figure 1, in order to add to the appearance of a finished installation. In the use of this form of mounting 12, a screen 0, with a binding strip or frame 32 which may be of metal or wood, is made in two sections and one placed above and one below the members, substantially as is shown in Figure 6.

Also, in this instance the supporting member 11', for the pivot pin 17, may be in the form of a suitable length of channel iron and be secured in sidewise relation to the inner side of the sash frame b, when the pivot pin 17 will be secured Theretaining plate 39 abutsjthe lowerside of in vertical position Within the channel and between the upper and lower flange positions of the member. j V

Referring now to Figure 7, the swivel 14," therein shown, will be provided with a transverse opening of the same cross-sectional area as that of the operator rod section 19", instead ofbeing made of elliptical form as in the firstinstance, while the stationary cross-pin 26, heretofore employed to engage the lateral slots 25 in the lower sides of the rod sections 19, will be replaced by a substantially T-shaped detent 26 .whichhas its cross-head disposed transversely of the swivel to engage in the lateral slots aforesaid and its leg portion depending into a vertical opening inthe lower side of the swivel body. A spring 33 is housed within the vertical opening and acts to tension the detent in an upward direction at all times.

However, when it is desired to manipulate the operator rod 19, the inner pendant portion thereof will be swung on the open hinge connection, then disposed at the inner side of the swivel l4", upwardly into horizontal position, during which movement the tongue portion of the hinge will force downwardly on the detent 26' and release the cross head portion of the same from engagement with the lateral slot in'the rod section at rest in the swivel. With the parts in this condition, the rod is free for fore and aft movement in the swivel 14". y

It will be understood that the positive locking members or devices 26 and 26 are alternativeforms and are separately employed in different constructions of the operators, each being of substantially equal effectiveness in lockingan operator to maintain a casement sash in any selected closed, open or partially open position of use. 7

It is to be particularly noted that the inner end section of the rod 19 will be moved to depending position when a sash is disposed in fully opened position, in order, of itself, to form a locking means and to brace the sash and its hinge supports against undue strain due to exterior forces, such as wind pressure, tending to move the sash further outward of the casing a from its adjusted fully open position. This rod portion, together with the knob 27, also provides a hand grip to facilitate the return of the fully opened sash to a closed or partially closed position when desired or necessary.

It is also to be noted that lengths of tubular stock may be employed in the construction of the, 1 operator members 19 in lieu ofv the solid rods shown.

In Figures 8 to 10 inclusive, a further modification of the device is shown, wherein the use of an enclosing casing for the swivel 14a is dispensed with and the latter is positioned directly within the opening in the frame 29a of the screen C.

In this instance of the invention, the swivel 14a preferably has its lower end only journalled in a bracket 36 projecting inwardly from the top side of the transverse support 12a to which it is secured, as by means of the fastenings or rivets 37. The lower cylindrical hub portion of the swivel 14a is fitted for turning movements in an opening in the projected end portion of the bracket 36,'with its end face disposed flush with retaining plate 39.

downwardly from its horizontally alined relation with respect to the outer end portion extended through the swivel for pivoted connection with the casement sash.

The opposite sides of the bifurcation,.thus

provided, act to prevent any accidental lateral or sidewise movements of the pendant portion of the'operator rod 19a, such as might otherwise result in the latter being sprung out of desired alined operative relation to the outer horizontal section of the rod leading through the swivel.

The swivel body 140. is generally cylindrical'in form and of a height and diameter to have snug rotative. movements within the frame 29a of the small opening in the screen C in order to close the screen. opening against the ingress of flies and other insects therethrough, particularly when the window sash is disposed in an open position. A passageway 15a is formed diametrically through the swivel body 14a for the outward projection therethrough, from the inner side of a window' casing and an inside screen therefor, .of. the

sectional operator rod 19a which has the outer end of the same pivotally connected to an out-' wardly swinging casement sash as aforesaid.

The opening of the passageway 1512., through the outwardly disposed side of the swivel 14a, is preferably elongated in the vertical direction sumcient only to allow the horizontally disposed length of operator rod 19a movement in such direction to release a notch in its lower side from a lock pin 26a, the latter extending transversely of the lower side of the passageway, prior to its endwise movement to open or close the easement sash.

The inwardly directed end portion of tha passageway 15a is likewise enlarged in the vertical direction and to a greater extent in order to allow for the required swinging movement of the theoperator rod 19a inwardly thereof and into alined relation with the normal horizontal portion of the latter. I

As in the other instances of the invention, the bringing of the pendant portion of the operator rod 19a: to horizontally alined relation to that portion of the same extending outwardly through the swivel 14a at the movement will result in the hinged portion 22a forcing downwardly on the pin 25a and lifting the operator rod bodily on the pivot connection with the easement sash.

This lifting movement, as hereinbefore stated, results in the freeing of the engaged notch at the lower side of the adjacent rod sectionfrom the lock pin 26a for the subsequent manipulation of the operator rod 19a to open and close the sash. r

In order to prevent accidental vertical movement of the operator rod 19a, when an inner end portionthereof is disposed in depending relation to that portion of the same engaged in the swivel 14a, the latter is formed to provide an inwardly projected portion 28s, at its upper end, and in closely spaced relation to the upper endof the hinged .portion22a of the uppermost section of pendant portion of the operator rod,

substantially asis shown in Figure 11.

Without further descriptiomit is thought that (ill of construction may be resorted to, without de parting from the spirit of the invention or its scope as claimed.
